PREOPERATIVE MEDICAL TESTS IN CATARACT SURGERY

Abstract
The objective of this study was to investigate whether routine medical testing before cataract surgery with local anesthesia reduces the rate of complications during the perioperative period. The scheduled cataract operation was randomly assigned either not to be preceded by routine medical testing (the selective-testing group) or to be preceded by routine testing (the routine-testing group). For patients assigned to the routine-testing group it was requested that a 12-lead electrocardiogram, measurements of hemoglobin and serum glucose be obtained. The sample of 1025 patients scheduled to undergo cataract surgery included 513 assigned to the selective-testing group and 512 assigned to the routine-testing group. The two groups had similar proportions of operations that were canceled and not rescheduled (2% in each group). The cumulative rate of medical events was similar in the two groups (9.6% in the routine-testing group and 9.7% in the selective-testing group; p = 0.923). The types of medical events were similar in both groups. The results of this study suggest that routine medical testing before cataract surgery does not reduce the rate of complications during the perioperative period, and a more efficient approach should be only to request preoperative tests indicated by patient history or physical examination.

Key words
Cataracts, utilization of health services, elderly, diagnostic tests, preoperative care.
